ABSTRACT = {Inheritance networks represent an important class of knowledge representation devices belonging to conceptual structures. Their primary purpose is to describe generalization/specialization relationships between classes and instances of concepts in the form of taxonomies. To make proper use of inheritance hierarchies in knowledge engineering logically consistency is required. Network representations need to be free of inconsistent interpretations. This work provides a formal dialogue framework for inheritance hierarchy construction which ensures that the network described to a system reflects the intentions of the operator. In situations where the dialogue leads to a network which contains mutually exclusive logical states we apply a nonmonotonic logic (NML) to explain inconsistency.},
